Bantu No 20-25 dong Makasih y

No.20. perbandingan mobil dan sepeda motor = 2:3
perbandingan mobil dan bus = 3:5
perbandingan = 6:9:15
bus = 15/30 × 300 = 150

no.21. panjang = 3/5 × 60 : 2
= 18 cm
lebar. = 2/5 × 60 : 2
= 12 cm
luas = p × l = 18 × 12
= 216 ( B )

Jawab:

Penjelasan dengan langkah-langkah:

20. 2/5 × 300 = 120

22. P×l = 36×24 = 864

P = 3/5×60 = 36

L = 2/5×60 =24

23.S = JP ×JS

=25/10 × 3000000

= 1 : 1200

24.JS = JP/S

=8/1 × 400000/1

= 3200000 CM

=32KM
